the process itself is relatively the same for both
the only difference would be that a supercharger is a lot safer than a turbo on na cars because you don't have the risk of detonation
on a turbo a boos spike is more common and it could blow your engine up but the supercharger is fizically attached to the crank there for it eliminates all the chances
i say supercharge it if you want to keep the stock internals or upgrade internals and get a turbo
i am also looking in to supercharging next year
the eaton m62 of the c230 merc is the best fit for out cars and it doesn't require inter cooler for that low boost
